The THAAD System is located in South Korea, and all rights to it belong to the United States of America. The task of destroying the THAAD System involves opposing two countries. Apart from the Destroyer with immense power, no one dares to undertake such a task. And the Destroyer who completes this task will prove their strength in the underworld.
This time, Yan Fei chose to strike South Korea, but he didn't mobilize his own body along with it, deploying only the Drone Avatar. To destroy the THAAD System, the drone could alone complete the task; there was absolutely no need for the body to be present. With the body not in the field, many dangers could be reduced. Even if this were a trap set by others, without the burden of his body, the drone could rely on its own mobility to safely escape.
